Falls are the most common cause of injury-related hospitalisation in older adults in the UK, and the consequences — particularly hip fractures, head injuries, and the loss of confidence that leads to reduced physical activity and accelerated functional decline — are serious and costly. While fall prevention programmes typically focus on exercise, home safety, and medication review, nutrition plays a significant and often underappreciated role in maintaining the muscle strength, balance, and bone density that prevent falls and reduce their consequences.
Vitamin D and Fall Risk
Vitamin D deficiency is one of the most consistent and modifiable risk factors for falls in older adults. Vitamin D supports muscle function through its receptors in muscle tissue — deficiency causes proximal muscle weakness (affecting hip and thigh muscles critical for balance and rising from a chair) and impairs proprioception (the body's sense of its own position). Multiple meta-analyses have found that vitamin D supplementation reduces fall risk by 20–30% in deficient older adults. The NHS falls prevention guidance specifically identifies vitamin D supplementation as a falls risk reduction intervention, and recommends 800–1000 IU daily for older adults at risk. This is one of the highest-return, lowest-cost interventions available in older adult health.
Protein and Muscle Strength for Fall Prevention
Sarcopenia — the age-related loss of muscle mass and strength — is the primary physical risk factor for falls. The relationship is direct: weaker muscles mean impaired balance, slower reaction time for corrective movements when balance is disturbed, and reduced ability to absorb the forces of a stumble without falling. Adequate dietary protein (1.2–1.6g per kg bodyweight daily) alongside resistance exercise is the most evidence-based approach to preserving the muscle mass and strength that protect against falls. The British Dietetic Association falls prevention nutritional guidance identifies protein adequacy as a top priority. See our sarcopenia prevention guide.
Calcium and Bone Density for Fracture Reduction
When falls do occur, bone mineral density determines whether they result in fractures. Osteoporosis — low bone mineral density — dramatically increases the fracture risk from falls that a person with healthy bone density would survive without serious injury. Adequate calcium intake throughout life, combined with vitamin D for absorption, is the primary nutritional approach to maintaining bone mineral density and reducing the fracture consequence of falls. Post-fall fracture rehabilitation also requires adequate protein and calcium nutrition — the process of fracture healing depletes both. See our bone density guide.
B12 and Neurological Function
Vitamin B12 deficiency — common in older adults due to reduced gastric acid production impairing absorption — affects neurological function including balance and gait. B12 deficiency causes subacute combined degeneration of the spinal cord, producing sensory and motor deficits that directly increase fall risk. Testing B12 status in older adults with balance difficulties or unexplained falls is important, and supplementation in crystalline (free) form (which doesn't require gastric acid for absorption) addresses the absorption problem of dietary B12 in this population. The NHS recommends B12 testing in older adults with relevant symptoms.
Hydration and Fall Risk
Dehydration causes hypotension (low blood pressure) that is particularly pronounced when standing up quickly (orthostatic hypotension) — a common cause of dizzy spells and falls in older adults. Chronic dehydration also impairs reaction time and cognitive function, slowing the corrective responses that prevent a stumble from becoming a fall. Adequate daily fluid intake is therefore a direct falls prevention measure. See our hydration in older adults guide.

Frequently asked questions
Is Vanda's Kitchen food suitable for older adults with swallowing difficulties?
Vanda's Kitchen supplies freshly prepared food to City of London offices rather than care settings, so the menu is not specifically designed for texture-modified diets. That said, many dishes include soft proteins, cooked vegetables, and rice-based dishes that are naturally easy to chew. For specific texture requirements, WhatsApp the kitchen to discuss what is available.
Can dietary changes alone prevent falls, or does exercise matter more?
The evidence is clear that both matter, and they work best together. Resistance exercise builds the muscle strength and balance that prevent falls, while nutrition — particularly protein, vitamin D, calcium, and B12 — provides the biological substrate for that muscle mass and bone density. Nutrition alone cannot substitute for physical activity, but physical activity programmes are significantly less effective when nutritional intake is inadequate.
How does vitamin D status affect muscle function specifically?
Vitamin D receptors are present in muscle tissue, and vitamin D deficiency causes a specific pattern of proximal muscle weakness affecting the hip flexors and thigh muscles most responsible for balance and the ability to rise from a chair. This weakness develops gradually and is often attributed to normal ageing rather than a correctable deficiency. Supplementation in deficient individuals can meaningfully restore this muscle function within weeks to months.
What is the recommended daily protein intake for older adults focused on fall prevention?
Current evidence, including British Dietetic Association guidance, supports 1.2-1.6g of protein per kilogram of bodyweight daily for older adults seeking to preserve muscle mass and strength. This is substantially above the 0.8g per kilogram standard recommended daily intake and requires deliberate dietary planning, particularly for older adults with reduced appetite. Distributing protein across three meals rather than concentrating it at one meal improves its use for muscle protein synthesis.
How quickly can dehydration cause orthostatic hypotension and dizziness?
Orthostatic hypotension — the blood pressure drop that causes dizziness when standing up quickly — can be triggered by relatively modest fluid deficits. Even mild dehydration of 1-2% of body weight reduces blood volume sufficiently to impair the cardiovascular system's ability to maintain blood pressure during postural changes. This can develop over a single morning without deliberate fluid intake and is particularly pronounced in older adults whose autonomic regulation of blood pressure is already less responsive.
